Here are some participants in day 2 of the NCAA tournament that I noticed bore more than a little resemblance to celebrities of some level:
Davidson's Stephen Curry, and poker professional Phil Ivey

Georgetown's Jonathan Wallace, and Cuba Gooding Jr.
Butler's Matt Howard, and MTV's Gauntlet Series' Evan Starkman
Western Kentucky's Ty Rogers, and former Indiana University star Tom Coverdale
North Carolina's Tyler Hansbrough, and WWE's Mike "The Miz" Mizanin
Siena coach Fran McCaffery, and U.S. Senator Mitch McConnell (R-KY)
And finally, CBS' Billy Packer, and the Cloverfield monster
